Title: Injection moulding process
IPC: B29C45/04
Filed: 1970-12-21
Abstract: 1339712 Injection moulding P A WOINARSKI 21 Dec 1970 [29 Jan 1970] 60477/70 Heading B5A An article is injection or transfer moulded from molten thermoplastic material, e.g. high density polyethylene, between first male and female mould parts and is retained on the male or within the female mould part during movement thereof along a linear or circular path for a final shaping and solidification by compression moulding in co-operation with a further mould part which is at a lower temperature than the co-operating or each first mould part. The further mould part may be of the same or different shape from the corresponding first mould part, and may act over part only of the moulded article. The mould parts may be maintained at the required temperature by temperature control fluids circulating through mould part passages. In the Fig. 2A embodiment, the male mould part is transversely reciprocable, e.g. by hydraulic, pneumatic or mechanical means, along a platen 10 between positions in alignment with a first fixed female mould part 17 (into which the material is injected), and with a further similar shaped fixed female mould part 18 in each position whereof it is reciprocable upon the platen 10, e.g. by hydraulic, pneumatic or mechanical means, into and out of moulding engagement with the mould parts 17, 18. Ejection of the moulded article is effected from the male part 16 by mechanical and/or pneumatic means. The male mould 16 may alternatively be fixed, with a pair of female moulds mounted for transverse reciprocation upon the platen 11. The male mould 16 is preferably maintained at a temperature equal to or less than the crystalline melt temperature of the material being injected, the first female mould is maintained at a temperature equal to or in excess of the crystalline melt temperature, and the further mould 18 is maintained at a temperature lower than that of the other moulds, e.g. room temperature. In the Fig. 3A to 3F embodiment (not printed), a pair of first male mould parts are mounted for transverse reciprocation across their platen between positions in which each thereof is alternatively in alignment with a first female mould part into which injection is effected and then each with a different one of a pair of further female mould parts, which are of shorter length than the first female mould part, to effect the final compression moulding shaping along part only of the moulded article. Fig. 4 (not printed) shows a similar embodiment to the Fig. 3A embodiment, but wherein the further female mould parts are mounted to their platen at adjustable resilient mounts or cushions. In the Fig. 5 embodiment, which is also similar to the Fig. 3A embodiment, portions 21, 22 of the first female and male mould parts are cooler than the remainder, of the mould parts, so that, e.g. a rim of a pail, is more rapidly cooled than the remainder thereof, the further female mould parts being configured to extrude material to provide an external change of shape below the rim.

Title: Embossing machines
Inventor: DEUTSCH FRITZ A
IPC: B41B11/00
Filed: 1969-12-15
Abstract: 1292862 Stereotype matrix machines ADDRESSOGRAPH MULTIGRAPH CORP 15 Dec 1969 [18 Dec 1968] 61024/69 Heading B6F Embossing machines.-An embossing machine in which a plastic or sheet metal article A is mounted on a carriage 26 movable in letterspacing and line-spacing directions, comprises male and female dies formed on a pair of discs 62-64 which are axially moved together before a manual or power embossing action is effected. Index setting arrangements.-The discs 62, 64 are rotated by a hand wheel 40 through bevel gearing 42, 44. Indication of setting is shown by a linear scale 54 on the front of the machine with which co-operates a pointer 52 driven by belt 46. Alternatively the scale may be a rotary dia. Impression arrangements.-Impression is effected by a motor or a hand lever 122, Fig. 12, rotating a shaft 124, collar 126, link 128 and second eccentric collar 130 to rotate a shaft 90. This rotates a cam 92 raising the lower disc 64 and then to force an embossing head 96 against the selected arms of discs 62, 64. The discs are axially moved to contact the article R before head 96 makes contact via lost-motion linkage 104 and cam 120 acting on the lower disc 64. Aligning for impression.-An aligning finger 140 is moved through a lost motion spring link 144 operated by a follower 150 from a cam 152. This action occurs before the cam 120 closes the two discs together. Adjustment of impression.-Adjustment may be effected by the screwed connection 132, Fig. 12, transmitting the impression force from the collar 126. Further adjustment may also be effected by a wedge (170, Fig. 16) which can vary the position of a stop on the anvil 88 or (188, Fig. 16). Framework.-The machine can be opened for access to the interior for replacement of the discs 62, 64. A cover section 24 is hingedly mounted on a base section 22, Fig. 15, and is held closed by a latch 164 pushed on a yoke 86 which is spring biased counterclockwise.

Title: Process and Equipment for improving the quality characteristics of Metal Strip
IPC: B21D1/05
Filed: 1978-10-31
Abstract: The quality characteristics of metal strip, especially electrical strip steel, are improved by stretch-bend straightening over bending rolls without gap-forming counterpressure rolls and subjecting to reverse plastic bending without the subsequent use of straightening rolls, the contact angle round the final bending roll alone being adjusted, independently of the contact angles round the preceding bending rolls, so that the metal strip is brought under fully plastic bending stress into the flat state, while any changes in the direction of the metal strip after the final bending roll are brought about entirely or substantially within the elastic state, leaving high residual stresses in the metal strip. <IMAGE>
Patent GB-2033584-A (GB)
Title: Accelerometers
IPC: G01P15/08
Filed: 1978-11-04
Abstract: A piezoelectric accelerometer comprising a piezoelectric element- mass-spring stack (16, 18, 24) uses the spring (24) as part of the electrical path from one side of the piezoelectric element (16) to an output terminal (38). The spring (24) is the only flexible component in this path, thereby avoiding the use of wires and enabling the component parts to be assembled by simple screw connections. The mass (18) is preferably of a high density tungsten alloy, thereby reducing the axial length of the mass. <IMAGE>

Title: Watch hand
IPC: B23K20/00
Filed: 1979-09-06
Abstract: A hand for a timepiece is formed in a two-layer construction, from a hard metal which is clad with a soft metal. The hard metal layer permits secure fixing of the hand to a shaft, as by a portion 12, while minimizing the possibility of deformation of the hand during such fixing. The soft metal layer can be easily formed into a desired pattern or be provided with a surface finish to provide an attractive appearance. The hand may thus be as thin as 30-50 microns and may for example be of nickel or stainless steel clad with gold or copper. The hands are blanked from a continuous strip using a diamond- tipped tool. <IMAGE>

Title: A locking cap for a threaded filler neck
IPC: B60K15/04
Filed: 1980-05-16
Abstract: A locking cap for a threaded filler neck includes a closure member (12) for engaging and closing the neck, a shell (50) providing a hand grip and including a key-operated lock (54), and a race (42) disposed for rotation between the shell and closure. The race (42) includes axially inwardly opening pockets (44), and the closure includes flexible pawl fingers (34) for engaging the pockets to provide a driving connection between the closure and race which is positive in the cap-removal direction and torque- limited in the cap-advancing direction. The race also includes a set of peripherally spaced, radially inwardly projecting teeth (47). A lock-controlled bolt mechanism (62) is mounted in a hub which is connected for rotation with the shell (50) and is removable by the lock to a cap-removal position. The bolt (74), Figure 7, of the bolt mechanism engages driving teeth (31) provided within the closure member. The driving teeth (31) are formed such that rotation of the shell in the cap-advancing direction, after the lock has been returned to the cap-locking position, cams the bolt out of engagement with the driving teeth. The hub also provides a pair of flexible drive fingers (92), Figure 8, for engaging the peripherally spaced and radially inwardly projecting teeth (47) to provide a driving connection between the shell (50) and race (42) which is positive in the cap-advancing direction and torque- limited in the cap-removal direction for free ratcheting of the cap when it is in position on the filler neck and locked. <IMAGE>
